Hi All,
How can you connect an external receiver to the antenna to work in parallel with the FLEX-6700? The rear panel has BNC Ant IN and Ant OUT sockets. How do you configure them in Smart SDR?

Try this: Using two short BNC jumpers and a female "T" BNC connector;  jumper a loop in to BNC "T" and loop out to other end of the BNC "T" then connect the second radio to the remaining female BNC "T" connection. In the ANT panel turn on the LOOP you connected to. You will have to determine if there are any negative effects on the Flex radio when activating the LOOP circuit to the second radio.  Let us know how it works.

Using a splitter is the right solution. Using a T-connector is not RF like

I would do neither. RF could jump the splitter network and damage your radio. The T connector is a definite no-no. There are a few T/R boxes out there that will take care what you want to do.

a splitter in RX pass of a TRX can what? Sorry, if it's true then all SDR stick user do it wrong, and also all preselector user.

Many Ham's worldwide use this technics and use Pan adapter via a SDR stick and SDR soft - and it works great.

Cant see the problem

What happens when you transmit. You have RF going straight into the receiver or SDR stick. As a matter of fact the SDR stick guys tell you to ground the antenna input to the SDR stick when transmitting.
Good Luck

Hi,
I bought Play SDR and I want to use it together with Flex 6700. On the BNC sockets the rx antenna on the back of the panel has no signal to the external receiver. It remains enabled for Play SDR a piece of wire as an antenna because I do not know if the use of the splitter after turning on the Flex6700 TC does not will damage Sdr Play. In Yaesu, the FT 3000 is on such a RX uot signal and a colleague works without a problem with the connected SDR Play.
